Product Overview

• Part No: 086349-002
• Brand: ABB
• Applicable System: ABB Advant AC31 classic PLC system, matched with 07 series CPU such as 07KT97H3
• Type: Rack-mounted digital output expansion module

• FunctionReceive logic commands sent by AC31 main CPU via CS31 system bus. Output DC24V switch signals to drive field actuators including solenoid valves, AC contactors, indicator lamps, alarm buzzers and cylinder electromagnetic switches. Realize on-site equipment execution actions according to PLC programs, cooperate with DI modules to complete full closed-loop automatic control of production lines. It features channel fault feedback for fast abnormal positioning of short-circuit and open-circuit wiring.

Core Features

• Total 16 independent digital output channels, grouped layout for convenient wiring grouping
• Each channel rated 0.5A at DC24V, capable of driving most conventional industrial small loads
• PCB conformal coating, anti-dust, moisture resistance and anti-electromagnetic interference, stable for chemical, metallurgy, workshop vibration environments
• Front panel LED status lights for each channel; power and module running indicators support rapid on-site troubleshooting
• Standard rack plug-in card structure connected through backplane bus, easy hot swap and maintenance without re-wiring
• Built-in channel overcurrent protection; single-channel short circuit will not burn the whole module

• Fully compatible with AC31 bus communication protocol, plug-and-play with AC31 rack slots
